WordPress cron job scheduler plugin
WordPress has a powerful built-in cron job tool which not many people know about. There is no option panel or screen where you can even create/view cron jobs.
We use cron jobs within our themes which helps automate certain tasks or events.
It's a bit tricky to setup and once you do, it's very difficult to tell if it's even working (without having to wait 1 hour or whatever your cron interval is).
So if you're at that stage and you'd like visibility into the cron system (or you're just curious), check out this great plugin called
Cron View.
It creates a separate page under your WordPress admin Tools and allows you to see all the pending scheduled cron jobs. You'll even see the default checks WordPress runs (which are twice a day I might add!).
Without this plugin, we'd be hosed and feel that WordPress should really build this into core for their developers to use. It will also help tremendously with debugging.
Read the WordPress Codex for details on how to use and setup the
wp_schedule_event function.
